Numerical Prediction of Wind Noise Around the Front Pillar of a Car-Like Body 931895

Surface pressure fluctuations on the front side window of a car-like body are numerically predicted by means of time-dependent Navier-Stokes simulation. The numerical results indicate that there is a critical inclination angle for the front pillar where the wind noise changes drastically. The related characteristics of turbulent flow structure are studied and show the mechanism of wind noise generation.
